I can't address wide feet but if the balls of your feet are bothering you, you check how you are pedaling. Most women pedal with the downward force on the balls of their feet (i.e.metarsal arch) which causes much pain. When you pedal downward be sure to push down with your heels not your toes. This will strengthen your stroke (it takes a bit of time to get used to this as you'll be using different muscles) and take the pressusre off your metarsals.

What kind of socks do you use? I have discovered light weight wool socks (Smart Wool) work the best for me as they breathe well.

I have Specialized shoes which I find quite comfortable. I also wear arch supports and have a metarsal arch button which will also take the pressure off your metarsals. I use a Look version for pedals.

Hopefully you have a LBS or two so you can try on different shoes. Some people have gone to mountain bike shoes as they are more flexible.
